The object of my invention is to produce a brick having anew ornamental effect, such new ornamental effect being the result of a from the forming machine and the subjection of the brick to the` fire, and preferably at a time betweenthe issuance of the clay column from the forming machine and the sub]ection dividualize the brick. y

The accompanying drawings illustrate my invention. I i

Fig. l isa general perspective view of a brick-forming machine capable of performingmy improved method and producingvthe new brick;

FiU. 2 is a perspective showingportions of the orming mechanism at the point where the novel step of my improved method is performed;

Fig. 3 is a perspective of the same portions of the mechanism shown in Fig. 2, but from another viewpoint, and

Fi 4 is a perspective of a group of the new rick.

In the drawings 1() indicates the columnforming mechanism, of common form, from which issues a continuous column of clay 11 the cross sectional dimensions of which are equal to two of the dimensions of the desired brick.

Arranged at the mouth'of the die across the top of column 11 is a cutting wire 12 so y positioned that it will separate a thin layer 13 of clay from the main body of the column, said layer being caused to over-ride the cuttin Wire and deflected ,down upon the top sur ace of the column 11 by a deflector 14. Thus far the mechanism is similar to that disclosed in the patent to Buckley, No. 1,207,- 272. In the operation of mechanism of this kind the layer 13 breaks up into comparatively narrow sections 15 which, inthe main, retain their continuity across the width of the column but are separated lengthwise of the column, these narrow bands or strips being of irregular widths and side outline, although, in a small percentage of the product,

these transverse strips are broken intermediate of thelr lengths. In the'1na1n,however,

they are fairly regular'and, when relncor` `porated with the clay'column, produce Vriblike proj ectionson the face of lthe brick which spacing.

' are'fairly regular in character alignment.I and l f The column 11 passes to the upper of an endless belt 16 ywhich transports it to the transverse cutting mechanism 17 f usual character, passing' preliminarily beneath a roller 18', covered with sheep-pelt, which has suliicient 4weight to cause whatever fragments may be llyingnpon the upper surface of the column to be re-adhered to the column. In order to produce my new producty I break the strips lat one ormore points intermediate of their len'gthsinto'fragments'15 and angularly shift these fragments upon the surface of the column, as clearly illustrated at the yright in Fig. 2 and at an intermediate point 'in Fig. 3, thesefragments 15 then passing under the pressure roller 18 and caused to adhere to the column. The column then passes through the transverse cutting mechanism v17 ,where the column is individualized intobricks and the individual bricks then pass beneath a pressure roller 20, the surface of which is kept moistened with oil sol that the top surfaces of thefragments 15 are glossed so that, in the process of burning, i

they-will be glossed as compared with the rough sub-sur ace-25 of theV face of the brick to which the fragments are adhered.-

It will be readily `understood that the breaking into fragments of the strips 15, and the angular shifting of the samemay beA accomplished in a number ofways and by a number of different mechanisms. In practice Ihave found `that very s atisfactoryand artistic results are obtainable by the use of` two light wire fingers26, 26y which, attheir upper ends are anchored upon across bar 27 beneathwhich the column passes on its way to the cutting mechanism, and the lower ends of whichare bent, as indicated at 26', to produceshort downwardly and rearwardly projecting lingers having lengths'k somewhat greater thanthe thickness of the strips 15. The cross bar 27 is conveniently angularly adjustable, about a horizontal axis, so that the free ends of the fingers "2G will project below the plane of the upper surfaces of the st-rips 15 and will just clear the upper surface of the 5 main body of the column so that these fingers, y

of the column. are broken into fragments, as

the column passes beneath the fingers, and these fragments are irregularly shifted alignlarly upon the face of the column.

As a result of the fragmentation and angular displacement of they pieces 15', and` their reincorporation with the main body ofthe.

clay, a brick is produced which, when laid in` a wall, looks as though it were covered withA a thin layer of leaves, as contrasted with the product disclosed in Patent No. 1,207,272 which, in practice, looks much as the bark of a rough-bark tree. The sub-surface of the finished brick, to which the fragments are adhered, will have a surface characteristic lvarying with the character of the element by means of which the fragment materialhas been separated from the main body of the column. lVhere a Wire is used for this sepa ration the sub-surface will be rough and the degree of roughness will increase with the diameter of lthe cutting wire.

I claim as my invention: .y

1. The method of producing a rough-face brick which consists in ejecting a column of suitable material, separating a thin layer of said material from the upper face ofthe column, breaking said thin layer into compara- 40 tivelyynarrow irregular strips, redepositing said strips upon the surface of the column from which the layer was removed, breaking said strips into fragments and angularly displacing said fragments, re-adhering the fragments tothe face of the `column from which they were removed, andsubjecting dimensioned portions of said column with its adhered fragments toa burning heat.

5o brick, which consists in ejecting a column of they were removed, subjecting theouter suri faces of said fragments to a treatment which will cause them, in the ultimate product, to have a smootherappearance than the exposed 55 sub-surface of the main body, and subjecting 2. The method of producing a rough-face l din'lensioned portions of said column with its adhered fragments to a burning heat.

3. The method defined in claim 1 wherein the fragmentation is accomplished along a line parallel with the vertical faces of the column. r

4. The method defined in claim 1 wherein the fragmentation and angular displacement of the strips is accomplished along a plural- ,ity of lines parallel with the vert-ical faces of the column by obstructing the flow of strips with the column at intermediate point in the lengths of thestrips.

5. As a new article of manufacture, a brick` one face of which is formed by a subsurface of the main body of the brick and by a multiplicity of irregular chips of the same material of uniform thickness and density adherent to the sub-surface and of lengths less than half the longest dimension of the' "85 face to which they are adherent and substany tially angularly displaced relative to the cross dimensions of said face.

6. As anew article of manufacture, a brick, one face of which is formed .by a sub-surface of the main body of the brick and by a multiplicity of irregular chips of the same material of uniform thickness and density adherent to the sub-surface and of lengths less than the longest dimension of the face to which they are 'adherent and substantially an-4 gularly displaced relative to the cross dimension of said face. .v

In witness whereof, I have hereunto set my hand at Indianapolis, Indiana, this'18th 100 day of December, A. D. one thousand nine hundred and thirty. y
